った。In the case of a conventional ready-made concrete pile, when a horizontal force such as seismic force is applied while having sufficient supporting force, the pile head directly connected to a building is usually used. There is a problem that the shear deformation becomes large and the concrete cracks or breaks at the portion. For this reason, considering the shear failure of the pile head, there was a problem that a strong pile had to be constructed, such as making the cross-section larger than necessary to reinforce the pile head, while having sufficient bearing capacity. .

を大きくできる。The concrete pillar with rubber chips bears the supporting force (vertical force) by the reinforcing cylinder and the concrete with rubber chips. Further, with respect to the horizontal force, in the rubber chip-containing concrete portion, the toughness is increased, and the shear deformation of the portion is increased, so that the shearing force acting on the pile can be reduced. For example, in ordinary concrete, 2500μ
The maximum stress level is reached at about the level, which leads to destruction, but in the case of a concrete column containing rubber chips, it can be extended to about 5000 μm. Further, the amount of energy absorption up to the destruction can be increased.
